In the present essay, commemorating the 60th anniversary of the publication of B. F. Skinner's "Verbal Behavior", I stand by and defend the judgment I expressed in my article "The Long Goodbye: Why B. F. Skinner's 'Verbal Behavior' Is Alive and Well on the 50th Anniversary of Its Publication" (2008c)--that Skinner's…

Jack Michael offered a course on verbal behavior almost every year throughout his teaching career. Jack was also interested in the application of Skinner's work and in 1976 began to offer a graduate course at Western Michigan University titled Verbal Behavior Applications. Jack and his students pursued the application of Skinner's work on verbal…

Children living in poverty face numerous challenges that negatively affect their wellbeing and thus their ability to learn. The consequences of poverty that interfere with students' learning include inattentiveness, demotivation, and feelings of powerlessness, shame, and anger. To reach these children, with the goal of helping them become healthy,…

Stefan Ramaekers and Joris Vlieghe's "Infants, childhood and language in Agamben and Cavell: education as transformation" is an insightful discussion of an important facet of educational experience. In the article, they consider a Fred Astaire dance sequence from the 1953 Vincente Minnelli film, "The Band Wagon," in combination…

In June this year, Wellesley High School became a focus of attention worldwide, following a graduation speech made by a teacher at the school. Departing from the traditional rhetoric of such ceremonies, English teacher David McCullough told the assembled graduates that they were neither special nor exceptional, but may well believe they were…

Barba's (2012) article deftly weaves three main themes in one argument about operant variability. From general theoretical considerations on operant behavior (Catania, 1973), Barba derives methodological guidelines about response differentiation and applies them to the study of operant variability. In the process, he uncovers unnoticed features of…

The target paper by Barba (2012) raises issues that were the focus of the author's first two publications on operant variability. The author will describe the main findings in those papers and then discuss Barba's specific arguments. Barba has argued against the operant nature of variability. (Contains 2 figures.)

In his article, the author claimed that studies of operant variability that use a lag-"n" or threshold procedure and measure the obtained variability through the change in U value fail to provide direct evidence that variability is an operant dimension of behavior. To do so, he adopted Catania's (1973) concept of the operant, which takes the…

Dr. Frank Gresham provides his reflections on a long and productive career in providing support to children with significant challenges. Dr. Gresham also provides his thoughts on the future of the field.

David Thorne's (2010) article, "The Identities Hidden In The Matching Laws, And Their Uses" performs a valuable service in pointing out alternative expressions of matching. However, some identities tend to obscure rather than illuminate empirical relationships. Three such problematic instances are discussed: interresponse time as a function of…

Some of the differences between Rachlin & Locey (2010) and Thorne (2010) are due to what assumptions are taken as givens versus questionable. Most of the other apparent differences are largely linguistic and can be resolved by agreeing on terminology. The identity combining both rate and probability of reinforcement is general, has already…

Historically, researchers have never quite been able to agree as to the role of emotions, if any, when behavior is selected by its consequences. A brief review of findings from several fields suggests that in contingency-shaped behavior, motivating events, often unconscious, seem needed for reinforcement to select behavior. In rule-governed…

The author agrees with Critchfield's ("Translational Contributions of the Experimental Analysis of Behavior," "The Behavior Analyst," v34, p3-17, 2011) thesis (to paraphrase): Behavior analysis must adapt; we cannot simply will ourselves into greater social relevance. Critchfield focused on the survival of the basic research arm of behavior…

A series of experiments on operant variability by Neuringer and colleagues (e.g., Neuringer, 1986, 2002; Page & Neuringer, 1985) have been repeatedly cited as showing that behavioral variability can be reinforced by making reinforcement contingent on it. They showed that the degree of variability in pigeons' eight-peck sequences, as measured by U…

School suspension is the most widely used disciplinary practice in U.S. schools. It is a programmatic regularity, as Seymour would say. He would also say "programmatic regularities have implicit or explicit outcomes." Like Seymour, the author is concerned about what he describes as the "frequent discrepancy between regularities and…
